Keeping a lithium-ion battery charged between 50% and 80% can offer several benefits, though this specific range is not as commonly emphasized as the 40-80% rule or the 20-80% rule. However, general principles applied to these broader ranges can still apply:
Benefits of Charging Between Lower and Upper Limits
- Reduced Stress and Degradation: Charging within lower to upper limits reduces stress on the battery by avoiding extreme conditions such as overcharging and deep discharging. This minimizes degradation and prolongs its lifespan.
- Improved Safety: Staying within a moderate charge range helps prevent overcharging, which can lead to increased heat generation and potential safety hazards like thermal runaway.
- Consistent Performance: By avoiding the extreme ends of the charge cycle, the battery maintains more consistent power output over its lifespan.
- Capacity Retention: Although not directly addressed in the 50-80% range, reducing the peak charge voltage and staying within a moderate SOC range can help retain more of the battery’s capacity over time.
While the 50-80% range is not specifically documented in the literature, adhering to the 20-80% or 40-80% rule is more commonly recommended for optimal battery life and performance. These practices help maintain a balance that reduces the risk of accelerated wear and tear while ensuring safety and efficiency.
